1 1/2 NKV UNI EN 1285 FIRE-FIGTING SETS WIT VERTIL PUMPS TENIL DT Operating range: from to 29 m 3 /h Pumped liquid: clean, free of solids and abrasives, non-viscous, nonaggressive, non-crystallised and chemically neutral, with properties similar to water. Pumped liquid temperature range: from -15 to 7. Maximum ambient temperature: + Maximum operating pressure: 1 bar (1 kpa) PN16 TENIL DT.Fire-fighting pump sets in accordance with UNI EN 1285 European Standard Fixed fire-fighting installations - utomatic sprinkler systems NOTES ON UNI EN 1285 UNI EN 1285, the Italian version of European Standard EN 1285, sets the design, installation and maintenance criteria for sprinkler systems.it replaces the earlier Italian standards UNI 989 and UNI 99. n automatic sprinkler system is designed to detect the presence of fire and extinguish it during the initial stages, or to keep flames under control until they can be extinguished fully using other means. The classic sprinkler system is composed of: a water source, a fire-fighting pump unit, a series of control valves, and a sprinkler circuit. MULTI-PUMP SET OMPOSITION The pumps of UNI EN 1285 sets will have the same characteristics; in addition: - if TWO pumps are installed, each pump must deliver the total system load (1 %), - if TREE pumps are installed, each pump must deliver 5 % of the load required by the design. In applications in which more than one pump is installed with higher or duplicated feed, only one of the pumps will be electrically driven (section 1.2 of the standard). In case of single water supply, there are no limitations on the number of electric pumps that can be installed. UNI EN 1285 FIRE-FIGTING PUMP SET OPERTION In normal conditions, (zero water request), the system is under static pressure. The first time there is a water request, the compensation pump activates (if present), reinstating the system pressure. In case of significant water request (activation of the fire-fighting sprinklers), the pressure drops until the two pressure switches connected in series activate the main pump. The two pressure switches must be calibrated to start the pumps at the following pressure values: ONE-PUMP SETS E.g.: Max pump pressure 1 bar - pump 1 starts at 8 bar, pump 2 starts at 6 bar P =,8 X MX PUMP PRESSURE TWO-PUMP SETS PUMP 1: P1 =,8 X MX PRESSURE PUMP 2: P2 =,6 X MX PRESSURE The main pump continues to operate until it is manually stopped using the STOP pushbutton on the electric control panel. In case of hydrant systems refer to UNI July 7. In addition to prescribing feed pumps in compliance with UNI EN 1285, UNI 1779 allows automatic stopping of the pumps 2 minutes after the closing of the hydrants, in case of non permanently supervised operation. D pump sets are suitable for sprinkler systems with manual stop, and for hydrant systems with automatic stop. PUMPS - UNI EN 1285 UNI EN 1285 (1.1) standard prescribes "orizontal or vertical pumps with coinciding maximum and zero flow rate head. They can be driven by electric motor or Diesel engine. For P and S pre-calculated systems, they shall be able to supply 1 % of the flow rate at 7 % of the head of the operating point (1 %). PRESSURE OMPENSTION PUMP - "JOKEY" The compensation pump (jockey) is a pump that intervenes when the collection of a small amount of water is required. This avoids pointless starts of the main pumps in case of small system leaks. D fire-fighting sets are available with and without jockey pump. WRNING - NOTE In case of higher or duplicated feed, only one electric pump can be used. ccording to the UNI EN (1.2) standard, In applications in which more than one pump is installed with higher or duplicated feed, only one of the pumps will be electrically driven.
